CARRIAGE-BOW.

SPECIFICATION forming part of Letters Patent No. 298,808, dated May 20, 1884.

Application filed September 14, 1883. (No model.)

To all whom, it may concern.-

Be it known that I, FREDERICK A. Win TIOH, a citizen of the United States, residing at Ashtabula, in the county of Ashtabula and State of Ohio, have invented certain new and useful Improvements in Carriage-Bows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in carriage-bows, and has for its object the provision of means whereby parts of said bows are so connected together as to combine great strength and durability with lightness and beauty.

To this end the invention relates more particularly to the means employed for securing the slat-iron to the inner wooden core or filler, and to the shape of the metallic covering and its combination with its inclosures.

My invention consists in the construction, combination, and arrangement of parts, substantially in the manner hereinafter described and claimed.

gimilar letters of reference in the several drawings indicate similar parts in said drawings.

Figure 1 represents the side piece of a how, the leather covering thereof being unstitchcd for a portion of its length to show the metal cover. Fig. 2 represents a longitudinal section through the lower end of the bow. Fig. 3 represents the blank of the metallic covering of the bow. Fig. 4. represents cross-sectional views on the line 3 y of Fig. 3 before and after the tips are formed. Fig. 5 represents a longitudinal sectional view taken through the thimble or ferrule which connects the slatiron to the filler. Fig. 6 represents a crosssectional view of the bow, taken on the line as a of Fig. 1. Fig. 7 represents graduated washers used in properly adjusting the slatiron.

In the drawings, A represents the bow in an inverted position; 13, the slat-iron, having the usual formation at Z), and

per end with a screw-threaded stud or tenon,

provided at its up- Z), which screws into the lower half of a thiinblc or ferrule, O.

0 represents a thimble or ferrule, the lower portion of which is made with thicker walls than the upper portion thereof, and said lower portion is provided upon its inner surface with female screw-threads which receive the screw-threaded stud b of the slat iron B. The upper portion of the ferrule 0 receives theten on (Z, the end of which preferably rests upon the shoulder a of the ferrule O. The outside surface of the filler is flush with the surface ofthe ferrule, and the ferrule O and filler D are inclosed by a metallic cover, E, which, when the bow is complete, is welded or otherwise firmly attached to the ferrule. The metallic cover E is in the shape of the blank shown in Fig. 3 that is, having cut-away portions 0 at top and bottom, whereby projecting lips c are formed at each side thereof, which, before the blankis made into tubular form, are bent, substantially as shown in Fig. l, after which the blank is turned into the form of a tube, and the edges 0 at top and bottom thereof are soldered or brazed together. The lips c are driven into a groove in the filler D.

f represents a metal clasp placed over the adjoining edges of the bow at the top thereof.

G represents a covering of leather or other material,which is stitched from top to bottom in the usual manner.

' It sometimes happens that the slat-iron when attached to the bow is found not to be in the same vertical plane with the longer of 8 the transverse axes of the bow, and therefore needs adjusting. To accomplish this and enable me to always force the threaded stud of the slat-iron home and still secure the slatiron and bow in the proper relative positions, I use washers H, of different degrees of thick ness, as shown in Fig. 7, which may consist of either solid or split rings H I, respectively. If, when the slat-iron is turned home in the ferrule, it is found to be one-fourth, oneeighth, &c., of a turn out of position, it is par tially removed and a split ring, I, of proper thickness is sprung apart and placed upon the tenon b of the slat-iron, between the shoulder 11 formed by said tenon and the lower end of the ferrule G, or the slat-iron is entirely removed from the ferrule when a solid ring, H,

is used. The. series of washers or rings are graduated in thickness with reference to the pitch of the thread on the lug of the slat-iron, whereby the turning home of the slat-iron suggests the combination of one or more of said rings therewith, which will bring the slat-iron and bow to the required position.

It will be observed that the joint between the filler D and the slat-iron B is covered by the ferrule O, and the joint between the filler D and ferrule O is covered by the metallic case E, by which breaking of joints the complete bow is rendered stronger and more durable than when the joint between the filler and slat-iron is alone covered by the metallic case,

, as will be readily understood and appreciated by those skilled in the art to which my invention appertains. It will also be readily understood that the lips 6, when driven into the groove, assist in keeping the filler in place, particularly in the event of shrinkage. The casing is inclosed in a casing or covering of leather or other material.

I have shown and described my preferred construction for carrying out my invention; but I would have it understood that I do not limit myself to the exact form and proportion of parts shown and described, as I am aware that modifications can be made therein without departing from the principle or sacrificing the advantages thereof.

I am aware that it is not broadly new to form a metallic case with lips which turn in and enter a groove in a wooden filler.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-.

1. In a carriage-bow, a ferrule having its lower inner portion provided with a screwthread to receive the slat-iron, and of greater thickness than its upper smooth portion,which receives the tenon of the wooden filler, in combination with the metal case, the lower edge of which is brought together and welded over said ferrule, as shown and described.

2. In a carriage-bow, the combination of the slat-iron having its upper end provided with a screw-threaded stud, b, a screw-threaded ferrule having the threaded portion upon its inner surface made thicker than the upper portion thereof, and filler D, having a tenon, d, upon its lower end, substantially as shown and described.

3'. In a carriage-bow, the combination of a ferrule which laps the joint between a filler and stud of a slat-iron, and a metal case which, at its lower end, is welded over said ferrule, and one or more washers, sustantially as and for the purpose described.

4. In a carriagebcw, the combination of a filler, a ferrule, and slat-iron, all arranged substantially as described, with the metallic case E, having inwardly-turned lips e, which extend from near the upper end of the filler to near the ferrule, the edges of the case at the ends thereof being welded together, substantially as and for the purpose set forth.

5. The combination of a filler, ferrule, slatiron, and metallic case, constructed substantially as herein described, with a casing of leather or other material, as and for the purpose set forth.

In testimony whereof I affix my signature in I presence of two witnesses.
